The 2020 Porsche GT3 Cup Challenge Canada by Yokohama scheduled was unveiled Friday as part of the International Motor Sports Association (IMSA) “State of the Series” at Road America.

Embarking on its 10th season of competition next year, the Porsche one-make series will keep its structure from 2018 with a Platinum class for 911 GT3 Cup cars built in 2017 or later and a Gold class for those built from 2014-2016. Every race will be 45 minutes in length.

As in years past, the 12-round calendar will kick off at the annual Victoria Day SpeedFest at Canadian Tire Motorsport Park on May 15-17. The holiday event weekend in Bowmanville, Ontario has been a staple for Porsche GT3 Cup Challenge Canada since 2012.

The series then travels south of the border to Watkins Glen, New York for the only joint event of the season with its American counterpart, Porsche GT3 Cup Challenge USA by Yokohama. The Sahlen’s Six Hours of The Glen weekend will take place on June 25-27 and will also host IMSA’s flagship series, the IMSA WeatherTech SportsCar Championship.

It’ll then be a two-week turnaround before returning alongside the IndyCar series as part of the Honda Indy Toronto street circuit. Rounds 5 and 6 will take place on July 10-12 to reach the halfway point of the season.

Toronto will be the first of back-to-back street races for Porsche GT3 Cup Challenge Canada, which will rejoin the Grand Prix de Trois-Rivières (GP3R) following a one-year absence. The series’ first trip of the season to Québec will take place on Aug. 7-9.

It’s been a longer hiatus – four years – since Porsche GT3 Cup Challenge Canada visited its next site, Calabogie Motorsports Park. Located just over an hour west of Ottawa, Calabogie will host Rounds 9 and 10 on Aug. 28-30.

For the second consecutive season, the Porsche GT3 Cup Challenge Canada will conclude at Quebec’s Circuit Mont-Tremblant with a pair of races on the weekend on Sept. 25-27.

“Porsche GT3 Cup Challenge Canada by Yokohama has been a fantastic platform to showcase the sports car racing talent in Canada and the on-track action has been nothing short of outstanding,” said IMSA Vice President of Marking David Pettit. “The caliber of the racetracks on the 2020 schedule exemplifies the quality of the series. All of us at IMSA are looking forward to another successful season with Porsche Canada and Yokohama.”
